【0019】本実施例は上記の如く構成するものにして、図10のフローチャート及び図11の出力線図に示す如く、前記設定器(99)で施肥量が設定されるとき、その設定施肥量b(kg/10a)が表示器(10 The present examples are to constitute as described above, as shown in the output diagram in the flowchart and 11 in FIG. 10, when the amount of fertilizer in the setter (99) is set, the setting amount of fertilizer b (kg / 10a) displays (10
1)に表示され、次に荷重センサ(98)の検出データがローパスフィルタ(104)を介し入力されるとき、 Appears in 1), then when the detection data of the load sensor (98) is input via a low pass filter (104),
検出データより一定時間(△t)当りの重量差(△W) Predetermined time from the detection data (△ t) per weight difference (△ W)
が変化量(施肥量)Q(f/s)(Q=△W/△t)として算出される。 There is calculated as the amount of change (fertilization) Q (f / s) (Q = △ W / △ t).

【0020】そしてこのとき、△t時間内の平均走行速度v(m/s)、作業幅L(m)(条数より決定される)とすると、単位面積当りの施肥量a(kg/10 [0020] Then at this time, △ average travel speed v (m / s) in the time t, when the working width L (m) (as determined from the number of threads), fertilization a (kg / 10 per unit area
a)は、a=Q/v×Lで算出され、この施肥量aを設定施肥量bに一致させる(b≒a)制御がモータ(9 a) is, a = Q / v calculated in × L, match the fertilization amount a set amount of fertilizer b (b ≒ a) control the motor (9
